Ages are calculated using 5568 years as the half-life of radiocarbon and are reported without reservoir corrections or calibration to calendar years.For freeware programs, we suggest that you look at the following web site for a list of programs that will calibrate radiocarbon results to calendar years (including making reservoir corrections).[ Radiocarbon-Related Information Sources] The error in the age is given by 8033 times the relative error in the Fm .Using this measurement also corrects for any mass-dependent fractionation within the AMS system.The Fraction Modern corrected for δC of a sample 10 separate times over the course of a run.Therefore a 1% error in fraction-modern leads to an 80 year error in the age.

While the three carbon isotopes are chemically indistinguishable, lighter C, reflecting the difference in mass.

Fractionation must be corrected for in order to make use of radiocarbon measurements as a chronometric tool for all parts of the biosphere.
